How to revert-to-parent handler mappings for an application on IIS 7 (or higher) by code?

Question

It is possible to revert handler mappings for an application to parent manually by following below steps:

• Select Application on IIS management console
• Double click Handler Mappings
• Clik Revert to Parent on the Actions pane

Is there a way achieve the same task programmatically (appcmd.exe, VBScript, C#..) ?

Note: If there is a custom setting already defined for the application, aspnet_regiis -i command does not work. The only way I have found so far is to remove application from IIS and add it again by code.

The following works for the question:

using System;
using System.Text;
using System.DirectoryServices;

namespace RevertToParentHandlerMappings
{
    class Program
    {
        static void Main(string[] args)
        {

            string vDirPath = "IIS://localhost/W3SVC/1/ROOT/AppName";

            DirectoryEntry vDir = new DirectoryEntry(vDirPath);

            vDir.Properties["ScriptMaps"].Clear();

            vDir.CommitChanges();

        }
    }
}
